Exterior window cleaning for Castlecrag homes
Castlecrag is in the Willoughby City Council area, about 40 minutes from our base in Elanora Heights. Castlecrag was designed by Walter Burley Griffin and Marion Mahony Griffin to sit within the sandstone and bush above Middle Harbour.
Timber frames and old putty don't like hard scrubbing or a flood of water. We use a soft brush and a low flow on older sashes and keep water away from flaking paint.
Downhill windows can sit high above the ground on sloping blocks. The pole reaches most of them from a safe footing, with no ladders on steep garden beds.
Trees drop pollen, sap and leaf dust on the outside panes, and spiders love sheltered frames. The brush lifts both, and pure water rinses them away without spots.
Castlecrag was designed by Walter Burley Griffin and Marion Mahony Griffin to sit within the sandstone and bush above Middle Harbour. The Griffin houses are built of local sandstone and much of the suburb is heritage-protected, with newer homes following strict design rules. Windows here are often original steel or timber, set deep into stone.
How often in Castlecrag
For most Castlecrag homes, exterior window cleaning is worth doing every 4 to 6 months. Pollen and sap settle fastest in spring and summer.

Working in Castlecrag
We use the gentlest effective method on Castlecrag homes: by hand on original frames, pure water on newer glass, and rinse water kept out of the bush and off the stone. Steep sites mean we plan access around the rock.

Our method
How we handle exterior windows

Nathan is punctual, knowledgeable, polite and left our place neat and tidy.
Step 01 of 04
Check access and glass
We walk the outside, note any scratches, failing coatings or etching, and plan hose runs so nothing crosses your gardens.

He was professional, responsive, and delivered exactly as promised.
Step 02 of 04
Scrub with the pole
The soft brush works over glass, frame and sill while pure water flows through it, lifting salt and grime.

Great work, fair pricing, and excellent communication.
Step 03 of 04
Rinse clean
A final pure-water rinse from the top of each pane carries the dirt away, frame first and glass last.

Excellent service! Nathan is punctual and nothing is a problem.
Step 04 of 04
Leave to dry
No squeegee and no cloth. The glass dries clear on its own, and we check it once it has.

Nathan just completed a pressure wash of our travertine pavers under our alfresco area, around the pool and the sundeck. What an absolutely fantastic job. Nathan is punctual, knowledgeable, polite and left our place neat and tidy. We will certainly be calling him back on a regular basis and can highly recommend him.
Nathan provided a reliable and professional property maintenance. Great work, fair pricing, and excellent communication. Highly recommend!
Nathan did a great job washing the external sides of our house. The weatherboard was dirty and had cobwebs. Nathan went above and beyond our expectations, the house was perfectly clean and all the cobwebs were gone.

How often should exterior window cleaning be done in Castlecrag?
For most Castlecrag homes, every 4 to 6 months. Pollen and sap settle fastest in spring and summer.
Do you offer exterior window cleaning across Castlecrag?
Yes. Castlecrag is about 40 minutes from our base in Elanora Heights, and we also work in Northbridge and Roseville nearby.
Can you clean windows on a Griffin house in Castlecrag?
Yes, gently. Original frames are cleaned by hand, and we keep water off the sandstone and joinery.
Do you keep water out of the bush?
Yes. Pure water carries no detergent, and we still direct run-off away from bushland.
Will the glass streak without a squeegee?
No. Deionised water has no minerals to leave behind, so it dries clear. That's the reason we use it.
Can you do the outside every few months and inside less often?
Yes, and that is what most coastal clients do. Outside every three months, inside once or twice a year.
Do you clean frames and sills?
Yes. The brush washes frames and sills with the glass, and we rinse salt out of the corners where it collects.
